Perhaps you should try some spelling variations:
oecd development » child development, oriented development
context working » content working, context looking, text working
center working » centred working, century working, inter working
working papers » working paper

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((oecd development) OR (based development)) center working papers ) OR ( ((oecd development) OR (based development)) context working papers )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((oecd development) OR (based development)) center working papers ) or ( ((oecd development) OR (based development)) context working papers ))".
• Adding a wildcard symbol may retrieve word variants: (( ((oecd development) OR (based development)) center working papers ) or ( ((oecd development) OR (based development)) context working papers ))*.
